Bombylius

"Bombylius" is a captivating genus of flies within the Bombyliidae family, often referred to as bee-flies due to their striking resemblance to bees and bumblebees. These flies are found worldwide, with one of the most notable species, Bombylius major, being prevalent across the northern hemisphere.

Bee-flies are frequently mistaken for bees because of their furry coats, which can range in color from yellow to orange. They possess long proboscises for sipping nectar, can fly swiftly, and have distinctive leg structures. However, their larvae are markedly different, as they are parasitic and invade the nests of solitary bees to feed on the food stores and grubs within.

In Europe, this genus includes various species classified under subgenera such as Bombylius and Zephyrectes. Noteworthy species include Bombylius major, Bombylius leucopygus, and Bombylius quadrifarius. There are also documented species in North America and other regions around the globe, each occupying distinct habitats.

The diversity within the Bombylius genus is remarkable, showcasing a wide array of bee-fly species that have adapted to various environments worldwide.
